UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.

An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This derivative is able to describe real-world problems with different scales or problems that change their properties during time and space, for instance, the spread of cancer; the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers and many others.”

Dr Karen Lazenby appointed as Registrar: Systems and Administration
2015-11-11


Dr Karen Lazenby, Registrar: Systems and Administration

Dr Karen Lazenby, former Director: Client Service Centre at the University of Pretoria (UP), was appointed as Registrar: Systems and Administration at the University of the Free State (UFS) as from 1 November 2015. She will be responsible for student enrolment, administration and services, and International Affairs.

“We are extremely fortunate to have a person of the calibre and experience of Dr Lazenby to join the senior team to help us create a 21st century student-centred management system using the best technologies available. She is without question the leader in her field, and the UFS is delighted to have her as part of the Kovsie community,” says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

Educational background

Dr Lazenby completed the BA (1992) and Honours (1993) degrees in English (cum laude) at the University of Potchefstroom before pursuing a Diploma in Tertiary Education (1996) and a Master's Degree in Computer Integrated Education (1998) at the University of Pretoria. She obtained a PhD in Education in 2003 on the topic ‘Technology and educational innovation: A case study of the virtual campus of the University of Pretoria’ and an Executive MBA from the University of Cape Town in 2006.

A track record to reckon with


Dr Lazenby started her career in higher education as a lecturer in Communication at the VaalTriangle Technikon in 1994, and was appointed as Head of Academic Staff Development the following year.  A year later, she joined Technikon SA as instructional designer at the Centre for Courseware Design and Development, and in 1997 she was appointed as Manager of Institutional Research. She was subsequently seconded to establish TSA Online and coordinate institutional technology. Dr Lazenby was appointed as a project manager at the department of Education Innovation at the University of Pretoria in 1998 where she implemented WebCT/Blackboard, online applications and payments, and student and lecturer portals (virtual campus). In 2000 she was appointed as Deputy Director: Electronic Education.

She was seconded by the UP Executive to establish the Client Service Centre in 2001 to provide integrated, efficient and effective services to students and other clients of the University. During her time as Director: Client Service Centre, she was inter alia, responsible for information and data governance, the intranet, website and call centre of the university, student recruitment, publications, application for study support, study finance, postgraduate scholarships, student accounts, payments, residence placement, access cards and parking, the graduate career office, and international student division. In 2005, she also acted as Director: Corporate Communication and Marketing.

Her vision for the UFS

“I would like to get the university's student administration to such a point that academic staff can focus on teaching and research. Streamlining the enrolment process so that we may see the necessary yield required in terms of our growth target as a university, is my other goal.” She added that capitalising on the strong international positioning of the UFS achieved by Prof Jansen, is a mission she intends to carry out. "I am grateful for the opportunity to work with Prof Jansen and the senior management team and am delighted to be part of the Kovsie community."

Dr Lazenby has published several articles and presented nineteen papers at international conferences.
